IPC: H04N11/20
Filed: 1989-06-12
Abstract: PURPOSE:To simplify circuit configuration by executing processing using a vertical filter after converting two systems of video chrominance signals into one system. CONSTITUTION:After two systems of analog input video chrominance signals 15, 16 are converted into digital signals by A/D converters 1, 2 respectively, they are converted into one system of a digital video chrominance signal 19 by being taken out alternately by every one line by a switch circuit 3. Then, after being band-limited through the vertical filter 4, it is led to three pieces of line memories 5 to 7, and the digital video chrominance signal 21 rearranged into desired order by one line unit by control signals 9 to 14 in the line memories 5 to 7 is derived. Thus, the circuit configuration can be simplified.

Title: Production method for removing anisotropy of crystal orientation in ferritic stainless steel wire or wire rod
Inventor: TANAHASHI TOSHIBUMI
IPC: B21C1/00
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To remove the anisotropy of crystals generated at the time of subjecting a cold-forged product to rolling by subjecting a hot-rolled wire material to thermal annealing at a specified temp. and then executing wire drawing operation at a specified reduction of area. SOLUTION: A material subjected to hot rolling to produce a ferritic stainless steel wire or wire rod is thermally annealed at 720 to 800 deg.C and is next subjected to wire drawing operation at >=40% area reduction. In the case the thermal annealing condition is <720 deg.C, the growth of the crystal grain size is not seen, and no sufficient softening for executing wire drawing in which the area reduction is high is obtd. Moreover, in the case of the annealing temp. exceeding 800 deg.C, duplex grain size is seen in the crystal grain size. The reason why the area reduction is controlled to >=40% is that, as the area reduction at the time of the wire drawing is made larger, the crystal grains are made finer, and the anisotropy of the crystal orientation generated at the time of the hot rolling is dissolved. In the case of <40% area reduction, small shape defects are seen at the time of the cold forging.

Abstract: PURPOSE:To prevent the generation of edge drops and to improve performance for controlling shapes by using split type eccentric rolls for the backup rolls of multistage cluster rolling mills, making intermediate rolls displaceable in an axial direction and forming crowns at both ends of the rolls. CONSTITUTION:In multistage cluster rolling mills, backup rolls 4 are split to plural rolls in an axial direction of stationary shafts 5a, and the axial centers of the respective split backup rolls 4' are off-centered. Crowns are adjusted by the entire part of the rolls 4' to eliminate medially high crowns. Intermediate rolls 3 are connected to moving devices via joints 3b and are moved axially. Crowns 3a are provided in both end parts of the barrel length of the rolls 3. The crowned parts 3a are adjusted of positions to the end parts of a plate material (a) to be rolled to shorten the effective supporting parts of work rolls 2 and to make the deformation of the rolls 2 in the plate thickness direction by the rolling load uniform and small. By such mechanism the generation of edge drops is eliminated.

Title: Soot removing device
Inventor: NAGASHIMA SEIJI
IPC: B08B7/02
Filed: 1978-12-06
Abstract: PURPOSE: To lengthen the life of the device, by forming a solid ball transport pipe in one straight form, and by absorbing difference in elongation by means of a joining portion between the solid ball transport pipe and a separator tank even when difference in elongation is generated due to the heat of the solid ball transport pipe and a boiler body.  
     CONSTITUTION: A damper 8 is opened, and solid balls in a separator tank 7 are scattered from an upper portion of a boiler through a shoot pipe 9, a distributor 10 and diffusing instruments 11. The solid balls scattered fall into a hopper 17 while repeating collisions with the internal elements of the boiler. Thus, soot is exfoliated by the impacts of the solid balls with the surfaces of the elements, and discharged from a chimney while being carried on the flows of gases. In this case, since a suction nozzle 5 and the tank 7 can be communicated by means of one straight pipe-like solid ball transport pipe 6 by horizontally installing a screw conveyor 2  o a lower portion of the hopper 17 and by mounting a small-sized solid ball tank 4 to the outlet port, difference in elongation due to heat can be absorbed by means of a joining portion between the solid ball transport pipe 6 and the tank 7.

Abstract: PURPOSE:To improve positioning precision of the leading end of a wire by forming the inner wall of a non-wire-gripping portion of a gripper pawl with a stepped portion having the dimension determined in consideration of the displacement of the diameter of the wire caused by the gripping force. CONSTITUTION:Gripping surfaces 12, 13 of gripper pawls 10a, 10b are respectively composed of portions 12a, 13a for directly contacting and gripping a wire 11 and portions 12b, 13b which do not contact the wire 11 and do not grip the same, and the non-wire-gripping portions 12b, 13b are formed with stepped portions 15a, 15b, respectively.
